(WJW) — LeBron James has tested positive for COVID-19 and was ruled out for the Los Angeles Lakers’ game against the Sacramento Kings on Tuesday night.

According to reports from TMZ Sports, James tested positive Tuesday afternoon and has been placed in the NBA’s health and safety protocols. Reports say he’s currently asymptomatic.

TMZ Sports reported that James tested positive using a lateral flow test. A follow-up PCR test came back negative, but then a third tie-breaker test came back positive.

James is likely looking at a minimum of 10 days away from the Lakers unless he returns two negative PCR tests in a 24-hour span.

Being placed in the NBA’s virus protocols almost certainly means James, who said earlier this season that he is vaccinated, either tested positive for COVID-19 or had an inconclusive result.

The news that he is missing time came on the same day that the NBA underscored its previous recommendation, echoed by the National Basketball Players Association, that coaches and players who are vaccinated receive a booster shot as soon as possible.

The NBA, in a memo obtained by The Associated Press, also told its teams Tuesday that it has documented 34 cases in which a fully vaccinated player, coach or staffer had a breakthrough case of COVID-19. The league has said about 97% of players are fully vaccinated. Brooklyn’s Kyrie Irving, who has not played this season because of his status, is among the exceptions.

Other NBA stars have already missed multiple games this season after testing positive, including Philadelphia’s Joel Embiid, who just missed three weeks while dealing with the virus.

Tuesday’s game marks James’ 12th absence in the Lakers’ first 23 games this season. He missed 10 games because of injuries and another because of the first NBA suspension of his 19-year career.

He’s averaging 25.8 points, 5.2 rebounds and 6.8 assists this season. If he is out for 10 days, he would miss at least four games.
